Looks like the PCV hose to me. I had a hole in mine right in there & it was causing a vaccumm leak which caused the car to idle wierd & die at stop signs sometimes. Replaced the hose & everything went back to normal.

Pcv hose, you can fix it with fuel hose from any auto parts store. "Big mike" is right, it will or is causing a vac leak.

Thats exactly correct. Pull it and grab some fuel line from the auto parts place and slip it inline where the cracked up piece is.

I would check all vacuum lines. If one is cracked, most likely there are more in the same condition.
